Fans of the US popstar, 23, flooded to a Paris concert hall for the singer's first show of her European tour since her Manchester concert was hit by a suicide bombing that killed 22 people on May 22.

There was a heavy police presence outside Paris' AccorHotels Arena, with roads surrounding the venue blocked off to traffic hours before the event was due to start.

Paris' police force confirmed that security measures were at their highest level.

Some young fans, including 15-year-old Lola and 16-year-old Edith from Paris, said they were reassured by the strong police presence, while others said they felt no fear at all following the Manchester attack and were present to show their solidarity and admiration for the 23-year-old U.S. star.

Edith said: "I must confess that I am still a little bit scared, but I am happy to be here so it's fine. The excitement sort of replaces the fear, but it's true that there is a part of me that is still a bit scared."

While Lola added: "For me, it's alright, because, precisely, after what happened, security has been reinforced even more, so for me, personally, it's alright."

Another 18-year-old fan shared: "And we had a final plan which was, during the song Problem, we plan to crack the luminous bracelets and to raise them to show our support, and it is also linked to the choreography that she created for the song in this tour."

Ahead of the concert Ariana shared an emotional message to fans, writing on social media: "First show back tonight. Thinking of our angels every step of the way. I love you with all my heart.

"Grateful for and incredibly proud of my band, dancers and entire crew. I love you, I love you."

And after she closed the show, she returned to Instagram to share: "Merci, Paris ♡ Je'taime Grateful to be back."

The singer had suspended the tour for her new album Dangerous Woman after the Manchester Arena attack, writing on Twitter at the time that she was "broken" over the tragedy adding: "I'm so, so sorry. I don't have words."

She cancelled subsequent shows before announcing her return just two weeks after the attack, to the delight of French fans.

Arian is due to play in Lyon for the next stop of her Dangerous Woman tour on Friday.
